This is known as hydrolysis. For further information, please see the related link.
It's called dissolution, a form of chemical weathering.
its called weathering, or erosion
yes there is such a thing as black granite
Weathering is the physical wearing down of rock or the earth, and erosion is the movement of the particles loosened by weathering. Weathering can be either mechanical or chemical. For chemical weathering to occur, a chemical reaction needs to occur in the ground, causing it to wear away. Mechanical weathering can include: freezing and thawing (water gets into ground and when it freezes it pushes the rock out), abrasion (force rubbing up against surface, such as water, which is why rocks in a river are so smooth), thermal weathering (rocks expand in very hot climates), salt wedges (rain with salt water in it falls into cracks between a rock and when the water dissolves, the salt is left behind pushing the rock outward), and animal activity (burrowing in the ground). Erosion would take place after one of these processes had, and it carries the weathered particles away by wind or water.
Not from the magma, no. Cooled and solidified magma is classified as igneous. However, metamorphic rocks can be formed as the heat and hot fluids of intruding magma affect the properties and possibly the chemistry of the existing "country rock" into which it comes in contact. This process is called contact metamorphism.
The component of granite that is not susceptible to chemical weathering is called Quartz!
Clay :p
Chemical weathering.
It's called chemical weathering. Think acid rain.
It is actually called weathering, but if your talking about the process of rocks breaking down into smaller pieces by physical means it is called Mechanical Weathering, by chemical means it is called Chemical Weathering.
The process is called chemical weathering.
It's called chemical weathering.
This process is called weathering.
It's called chemical weathering.
RUST

The process is called rusting.
